Spit | coastal feature | Britannica This will create a clear revision resource which they can easily use to consolidate learning and . The tectonic plate movements, volcanic activity and other geologic events which eventually lead to the fusion of the separate land forms at sea, results in the formation of a continuos narrow strip of land, which is bounded on either side by a body of water.

It does not store any personal data. Ridgesare areas of the foreshore that are raised above the adjacent shore which dips into a runnel. This causes a collision of wave fronts on the landward side, cancelling each other out and producing a zone of still, calm water where deposition occurs, between the island and the coast.

Identify this coastal landform. Join us today, Society membership is open to anyone with a passion for geography, Royal Geographical Society As sand dunes become colonised with vegetation roots stabilise the sand and hold it together. At the turn, longshore drift continues in the original direction, but its energy is dispersed, lost as the wave refracts and the current spreads, leading to deposition on the sea bed.
